Answer:
A) 6^2 + 11^2 is not equal to 15^2
Step-by-step explanation:
To find out if a right triangle is a right triangle you have to use the Pythagorean Theorem, like it is used in A.
6^2 + 11^2 = 15^2
36 + 121 = 225
157 does not equal 225
So this is not a right triangle
Answer:
Inverse proportionality relationship
Step-by-step explanation:
SInce I equals 50 divided by t, we see "t in the denominator, which corresponds to an INVERSE proportionality between these variables (I and t)
This is what the graph would look like
Answer:
Daylily: $9
Geranium: $2
Step-by-step explanation:
1 daylily costs x.
1 geranium costs y.
11x + 4y = 107
4x + 12y = 60
Multiply the first equation by 3 and subtract the second equation from it.
29x = 261
x = 9
4x + 12y = 60
4(9) + 12y = 60
12y = 24
y = 2
Answer:
Daylily: $9
Geranium: $2
